This Church of Ireland church dates from 1812 and is named for St Thomas Lindsay of Armagh. The first church here was founded in 580 AD, with a monastic settlement that was raided and eventually destroyed by the Vikings. The graveyard is for all denominations; here lies Rev John Gage, who bought the island in 1746. War graves hold the crew of HMS Viknor, lost in 1915 probably sunk by a mine, and HMS Racoon, which hit the rocks in 1918. Church services are held every Sunday in July and August at 11AM, and monthly Sep-Jun.
